LAMP-CANOPY.

Specificationof Letters Patent.

Patented June 10, 1919.

Application filed March 1, 1917. Serial No. 151,702.

To all whom it may concern:

Be it known that I, SAMUEL HEATH, a citizen of the United States, residing at Roxborough, in the county of Philadelphia and State of Pennsylvania, have. invented new and useful Improvements in Lamp- Canopies, of which the following is a specification.

My invention relates to new and useful improvements in lamp canopies, and has for its object to provide an exceedingly simple and effective device of this character which may be attached to gas fixtures or the chimneys of oil or gas lamps, whereby the unconsumed combustible material passing up a lamp chimney or from a gas light will be burned, thus preventing the Walls or ceilings of buildings from becoming smoked and dirty, and which will also deflect the heat from the upper parts of the fixture, so that a person will not be burned when regulating the flow of gas or air.

A further object of the invention is to provide a device of the character stated comprising a frame, in which is situated a sheet of mica adapted to be heated by the heat from the light, so that the unconsumed oombustible material in coming in contact with the highly heated mica will be consumed.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by numeral to the accompanying drawing forming a part of this specification, in which- Figure 1, is a side elevation of a gas fixture showing my improved lamp canopy applied thereto.

Fig. 2, is an enlarged bottom plan View thereof.

Fig. 3, is a transverse sectional view thereof.

Fig. 1, is a side elevation of a chimney showing a slightly modified form of my canopy applied thereto.

Fig. 5, is an enlarged bottom plan view thereof; and

Fig. 6, is a transverse sectional View thereof.

In carrying out my invention as here embodied 2 represents a gas fixture having the ordinary hood 3, to which is attached the globe 4E. At the present time hoods 8 are provided with openings 5 approximately half way around the circumference, the balance being left solid in an endeavor to keep the heat from the gas key, but with little or no success, and since one half of the hood is solid the draft through the lamp is partly shut off and deflected, so that the light burns unsatisfactorily, but by the use of my invention the hood 3 may be provided with holes 5 entirely around its circumference, thus giving the proper draft, so thatthe light will burn evenly and brightly.

The canopy is represented by the reference numeral 6 and consists of the inverted saucer shaped frame or cap 7 having a central opening 8, a sheet or disk of mica 9, having a central opening 10 and a perforated plate 11. The mica and perforated plate are spaced inside of the frame with the mica between said frame and plate, and these are held in place by teats or indentations 12, formed in the flange of the frame.

The perforated plate 11 is also provided with a central opening 13, and through said opening 13 and the openings 8 and 10 passes the gas pipe of the fixture when the canopy is mounted in position.

In practice the unconsumed combustible material passes upward through the openings in the hood, where they are mixed with the surrounding air, which adds oxygen to said material, and when these pass through the perforated plate and come in contact with the heated mica, they are immediately consumed, thus preventing the surrounding walls from becoming dirty and smutty.

The canopy also deflects the heat arising from the light and prevents the contact of said heat with the gas key and other parts of the fixture, so that a person using the same will not be burned.

In Figs. 4: to 6 I have shown a slightly modified form of my invention which is constructed in a similar manner, but has no central opening for its attachment to a fixture. To the frame or cap are attached a number of depending brackets or arms 14 which are bent inward at right angles to form rests 15, the ends of which are again bent at right angles to form fingers as at 16, which are adapted to be inserted in a chimney '17, so that the same may be supported above the outlet end thereof in the line of the draft.

The operation of this form of my device is the same as heretofore described, in the form illustrated in Figs. 1 to 8 inclusive. I

Of course I do not wish to be limited to the exact details of construction as herein shown, as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful, is-

1. In a lamp canopy a frame or cap having a central opening, a sheet of mica situ- Copies of this patent may 'be obtained for a perforated plate having a central opening situated in the frame for holding'the mica V in position, and indentations formed in the flange of the frame for holding the perforated plate in place.

2. In a lamp canopy, a frame or cap having; a flange, a sheet of mica situated therein, a perforated plate situated in the frame for holding the mica in place and indentations formed in the flange of the frame for holding the perforated plate in position.

In testimony whereof, I have hereunto affixed my signature. p,

SAMUEL HEATH.
